Current situation - basicsCurrent situation - basics
Part 1 of IEC 61360 published in 1995

First revision of Part 1 as CDV in 2000 with extensions
First revision of Part 2 as CDV in 2000 with corrections to original issue
New Part 5 circulated as CD covering EXPRESS model for extensions to Part 1
New issue of IEC 61360-1New issue of IEC 61360-1
New data types LIST, SET, ARRAY
Improved definition of TERM
Explanation of use of feature class
Part 2 corrected and terms deleted
New Part 5 to contain EXPRESS model for new dictionary data types and terms
EXPRESS code for instances of new data types in annex to Part 5
Current situation - dictionaryCurrent situation - dictionary
Part 4 of IEC 61360 (core dictionary) published in 1997 - 250 classes and 1000 definitions
First drafts of extensions to Part 4 - proposals for 1000 more definitions
Maintenance and ValidationMaintenance and Validation
Part 3 of IEC 61360 published in 1997 as a Technical Report
Principles of validation by IEC TCs accepted
Maintenance agency and on-line database to be set up in IEC CO
Relationship with ISORelationship with ISO
Complementary standard - ISO 13584ISO 13584-42 = IEC 61360-2ISO 13584-24 - PLIB standard
provides model for instancesDiscussions on incorporating
extensions to IEC 61360 in new parts of ISO 13584

Si2/ECIX consortium (1) Si2/ECIX consortium (1)
Seven or eight partners - mostly USAInitial objective to produce electronic
data booksExchange format initially SGML -
now XMLExpressed interest in IEC dictionary,
but were concerned over copyright issues
Si2/ECIX consortium (2)Si2/ECIX consortium (2)
EXPRESSO parser for SPF files publicly available from NIST
Conversion tool SPF to SGML and XML publicly available from NIST
MoU about to be signed with IEC for use of IEC dictionary
ECALS/EIAJ consortium (1)ECALS/EIAJ consortium (1)
Over 30 companies - part funded by MITI
Administration now in the hands of EIAJ
Primary objective - exchange of component data in computer-sensible form
ECALS/EIAJ consortium (2)ECALS/EIAJ consortium (2)
Needed a dictionaryExamined alternatives - considered
IEC dictionaryRejected IEC dictionary due to
concern over copyright issuesDecided to produce own dictionary
The ECALS/EIAJ dictionaryThe ECALS/EIAJ dictionary
Around 450 classes and 2000 definitions
Not entirely compliant with IEC 61360-1
Available as EXCEL spreadsheetExchange format proposed to be
XML - also considering CSV and SPF

RosettaNet (1)RosettaNet (1)
Membership now more than 50 firms in USA with expansion in Europe and Japan
Objective - e-commerce in component data over the whole supply chain
Needed a dictionary in short time scale
Examined alternatives - IEC and ECALS
RosettaNet (2)RosettaNet (2)
Chose to use ECALS/EIAJ dictionary with XML implementation - concern over IEC copyright issues
Reconsidered decision - turned to Si2 for help
Current implementation still based on ECALS/EIAJ with some amendments
RosettaNet (3)RosettaNet (3)
RosettaNet dictionary available on the Web
Stand-alone version also availableXML and PDF output availableMaintenance a continuous processOnly partially compliant with
IEC 61360
JEMA project (1)JEMA project (1)
Heavy electrical industry cross-over project
Project from April 2000 to March 2001 - sponsored by MITI
Members from four trade associations in Japan
JEMA project (2)JEMA project (2)
Three themes -– standardization of EC/EDI/SCM– standardization of catalogue of heavy
electrical components– standardization of engineering documents
Implementation based on IEC 61360 and ISO/PLIB
Getting togetherGetting together
First meeting of all interested parties in Paris in March 2000– attended by IEC CO, MERCI, Si2/ECIX,
ECALS/EIAJ, RosettaNet
Meeting in USA this week – involving Si2, RosettaNet, EIAJ - IEC not
represented
Need to convene further meetings of all parties in near future
ActionsActions
Maintenance and validationBusiness modelCopyrightExpand dictionaryPromotion of dictionary
Maintenance and validation (1)Maintenance and validation (1)
Establish IEC on-line dictionary– downloads essential
Establish maintenance procedures– regional groups feeding IEC CO
– perform syntactic checks– templates for data entry, with syntactic
check– Amend IEC 61360 Part 3
Maintenance and validation (2)Maintenance and validation (2)
Establish validation procedures– requests to IEC TCs– local validation, related to local
maintenance groups– model similar to that for IEC 60617
Business modelBusiness model
Business model for the IEC dictionary– subscriptions by member firms, e.g.
$1000 pa– members have rights to request new entries
and to make downloads– dictionary display restricted for non-members– define the role of national committees
Copyright issuesCopyright issues
Make dictionary free if possibleLicence conditions
– may not sell– may not modify– must acknowledge source– must declare extensions– must impose same conditions on others
when passing on
ExpansionExpansion
Introduce new DETs into the IEC dictionary as quickly as possible
Bring the ECALS/EIAJ dictionary into the IEC dictionary
Look for other potential sources of dictionary data
